Abstract

PURPOSE: A method for controlling the call request of a caller by a callee of a mobile communication system is provided to prohibit a prank call, a wrong number, or the origination from a user who does not want call. CONSTITUTION: A receipt-side terminal sets a call limit function and a password. When a call is requested from a transmission-side terminal, a base station receives call limit function setting information and the password from the corresponding receipt-side terminal. The base station requests the input of a password to the transmission-side terminal and compares the inputted password with the set password. If the inputted password is identical to the set password, the base station pages a receipt-side subscriber and forms a channel. If the inputted password is identical to the set password, the base station converts the transmission side and the receipt side into the standby state.

Description

Method of controlling caller's call request by receiver in mobile communication system {CALLER ACCESS DENIED SYSTEM IN MOBILE COMMUNICATION SYSTEM}

The present invention relates to a method for controlling a call request of a caller by a receiver in a mobile communication system.

The present invention performs control through the base station to reject or allow a call request of the calling party at the receiving side, and when a call request at the calling party inputs a password matched with a preset password to allow the call at the receiving party. Only when the base station rings the receiver and establishes a call line between the calling party and the receiving party, the caller's call request control by the receiver of the mobile communication system allows the receiving party to control the calling request of the calling party. It is about a method.

1 is a diagram showing a schematic configuration of a base station 101 and a terminal 102 in a mobile communication system, in particular, a mobile telephone system.

The mobile phone terminal 102 includes a transceiver 103 for RF communication with a base station, a controller 104 for signal transmission and reception, a display unit 105 for displaying a terminal operation, and a terminal for user manipulation. Key input section 106, and a memory 107 for storing data.

In order to make a phone call, the other party's subscriber's telephone number to be called is input using the key input unit 106 of the terminal 102, and the control unit 104 controls the transceiver unit 103 to transmit the corresponding information to the base station 101. send.

The base station 101 receives the information and makes a call by calling a wireless or wired subscriber station 108 which desires to call.

That is, when a caller presses a telephone number and presses a call button, the terminal sends an access channel origination message to the base station, and the base station sends a page message to the receiving side. The receiving side sends a page response message to the base station, which receives the message, connects a traffic channel in both directions, and rings through an Alert with information message.

As described above, the counterpart subscriber is unilaterally called by the request of the subscriber who wants to talk.

The one-sided call as described above is uncomfortable because you have to take a prank call or a wrong call.

In order to solve this inconvenience, a terminal having a function of providing a caller ID and receiving the call and checking the other party's number is not proposed, but a terminal having this function is also proposed. One-sided ringing (or vibration) could not be rejected.

That is, once a call is made from the other party, the phone rings or vibrates to notify the call unless the terminal is turned off.

The present invention proposes a method of controlling a caller's call request by a receiver of a mobile communication system, which allows a receiver to reject a call request (ring tone (vibration) output of a subscriber terminal) itself with respect to a call request of a caller.

According to the present invention, when a subscriber sets a password for call control in his terminal, the base station requires a password input for a call request of another subscriber who wants to talk with the subscriber, and the subscriber is requested only when the password matches. The present invention proposes a call request control method of a caller by a receiver of a mobile communication system which allows a caller to control a call request of a caller at a receiving end by controlling a call (output of a ringing tone (vibration) of the subscriber terminal).

Method of controlling caller's call request by receiver of mobile communication system of present invention, (a). Setting a call restriction function and a password at the receiving terminal, (b). When the call request from the calling terminal, the base station receives the call restriction function setting information and the password from the corresponding receiving terminal, (c). Requesting a password input from the calling terminal and comparing the input password with the set password, (d). If the password is matched at the base station, calling the subscriber to make a call path, and if the password is not matched, switching both the transmitting side and the receiving side to the standby state; Call control method of the caller by the receiver of the mobile communication system characterized in that the control.

In the method of controlling the caller's call request by the receiver of the mobile communication system of the present invention, the password is received by re-input within a predetermined allowable number of passwords inputted from the calling terminal, and the passwords are compared.

In addition, in the method for controlling the caller's call request by the receiver of the mobile communication system of the present invention, a message for requesting the sender of the password to the calling party, a message notifying that the password is identical or inconsistent, a message containing the password input from the calling party, The message for returning to the standby state is divided according to a record type of a flash with information message.

The present invention is based on the premise that the mobile subscriber has previously given the password to another special user who will accept the call.

2 is a flowchart showing the operation procedure of a receiving terminal, a base station and a calling terminal according to the present invention.

First, the subscriber terminal of the receiving side is configured for the call restriction function and password for the present invention.

The call restriction function and the password setting are made by the key input unit 106 in FIG. 1, and are realized by the controller 104 recognizing a key input according to the menu promised.

The setting of the call restriction function and the password are stored in the memory 107. The memory 107 is a nonvolatile memory.

The calling party's subscriber terminal inputs the phone number of the other party's subscriber (receiving party) who wishes to talk and presses the call button.

The originating terminal then transmits an access channel origination message to the base station. The base station calls the other party's receiving terminal from which the calling terminal desires to talk. The call of the receiving terminal is made using a page message or a slotted page message.

The control unit of the terminal receiving the call from the base station refers to the memory and searches whether the call limit function is currently set in the terminal.

When the call restriction function is set, the receiving terminal transmits a password to the base station together with the call restriction function setting information so as to request a password input.

This message is delivered using a Flash with information message, depending on the record type.

The base station receiving the call limit function setting information and the password message recognizes that the call limit function is set, and requests the caller to input a password.

The password entry request is delivered using a Flash with information message, depending on the record type.

In addition, when requesting a password input from the calling terminal, the base station uses a voice message prepared in advance.

A caller who is requested to input a password inputs a password using his own terminal, and the input password is transmitted to a base station using a flash with information message, depending on the record type.

With respect to the password transmitted from the originating terminal to the base station, the base station compares whether the input password matches the set password of the receiving terminal.

As a result of comparing the password, if the password set in the receiving terminal and the password inputted in the calling terminal do not match, the password is re-entered at a predetermined number of allowable times, for example, three times.

If the password does not match, the base station sends a message indicating that the password does not match to both the calling terminal and the receiving terminal to return to the standby state through the record type of the information message flash.

This blocks the calling terminal from making a call to the receiving terminal, and the receiving terminal does not even make a ringing tone (such as a bell or vibration).

On the other hand, as a result of comparing the password, if the password set in the receiving terminal and the password input from the calling terminal is matched, the base station notifies the receiving terminal of the password through the record type of the information message flash.

The receiving terminal receiving the password matching message sends a page response message, and the base station establishes a communication path between the calling terminal and the receiving terminal so that the caller and the receiver can talk.

3 is a flowchart showing the control procedure of the base station in the present invention.

When the base station receives the access channel message from the originating terminal, the base station clears the allowable number counter for the password input guidance to '0' and calls the receiving terminal to receive the call restriction function setting and the password message from the receiving terminal.

Then, a password input is requested to the calling terminal as a voice message.

The password transmitted from the calling terminal is compared with the password of the called terminal to determine whether the password matches.

If the password does not match, increase the counter value by '1' and compare the counter value with the allowable number of '3'.

If the password is within the allowed number of times (3 times), the password is re-entered at the calling terminal.If the password inputted by the calling terminal does not match the set password even within the allowed number, the calling terminal and the receiving terminal are asked to return to the standby state. send.

However, if the input password received from the base station matches the set password of the receiving terminal within the allowed number of times, the base station sends a message indicating that the passwords match, and receives the page response message of the receiving terminal. It receives a message and connects a traffic channel in both directions and rings a ring through an Alert with information message to make a call.

4 is a flowchart showing the control procedure of the receiving terminal in the present invention.

When the terminal call message is transmitted from the base station to the receiving terminal, the terminal determines whether the call restriction function is currently set, and if the call restriction function is not set, sends a page response message to the base station, and the base station receives the message. A traffic channel is connected in both directions and a ring is issued through an Alert with information message to allow a call to be made between a calling party and a receiving party.

However, if the call restriction function is set, the receiving terminal delivers the call restriction function setting message and the password message to the base station.

Then, it is determined whether a message indicating a password match is transmitted from the base station.

When a message indicating a password match is received from the base station, the receiving terminal sends a page response message to the base station, and the base station receives the message, establishes a traffic channel in both directions, and sends an Alert with information message. Ring the ring through to make a call.

When a message indicating a password mismatch is received from the base station, the receiving terminal returns to the standby state.

5 is a flowchart showing the control procedure of the calling terminal in the present invention.

The calling terminal inputs and transmits the telephone number of the other party subscriber (receiving terminal) that wants to talk.

If the call receiving function of the other party's receiving terminal is set, the base station receives (listens) a voice message for inputting a password.

In response to this voice message, the caller enters a password and sends it. As a result of the password determination at the base station, if the password input by the calling terminal and the setting password of the receiving terminal match, the call is made.

Therefore, if you know the password of the other party subscriber who wants to call in advance, that is, only the user who is allowed to call will be able to talk to the subscriber, and even the call of the other subscriber itself will be blocked without knowing the password. Even if there is a call or a wrong call, an unnecessary terminal reception notification operation such as ringing or vibration is excluded.

According to the present invention, it is possible to prohibit an outgoing call, a wrongly placed call, or a call from a user who does not wish to make a call, and an alarm message for ringing a call for a call from a user who does not wish to make a call. There is no need to receive a message) and there is no ringtone itself.

According to the present invention, important people such as family members, relatives and friends can be telephoned in advance by informing them of their passwords, but they can block calls from people who do not want to talk without turning off the phone.

The receiving base station can also control the origination without setting up the traffic channel, eliminating the need to reduce the number of subscribers occupying the traffic channel.
